Lab 9 Heat of Reaction
OBJECTIVE:
To experimentally determine the heat of reaction for two
exothermic reactions.
DISCUSSION:
The heat given off or gained in a reaction is called the heat
of reaction (∆?????????).
A reaction that releases heat is known as an exothermic
reaction; an endothermic reaction
is one that absorbs heat.
The heat of the reaction corresponds to one mole of the
reactant and is expressed in
kilocalories per mole of reactant or in kilojoules per mole of...

1. Read the write up through the Data Analysis section. A student carried out the experiment described there. The student used 0.4894 g of Mg in the first reaction and found that the temperature of the solution went from 22.1 to 42.7'C. In the second reaction, 0.803 g of Mgo was used and the solution went from 22.7 to 28.7*C. Calculate the following. Show all calculations. AH, The enthalpy of the reaction of magnesium with acid. AT = Mass of...
